So when she reads about a Harvard scientist's prediction that an asteroid will strike Earth in April, Eleanor knows her family will be prepared. Her classmates? They're on their own! Eleanor has just one friend she wants to keep safe: Mack. They've been best friends since kindergarten, even though he's more of a smiley emoji and she's more of an eye-roll emoji.

But the story the whole world wants to tell about Simon is the one he'd do anything to forget: the story in which he's the only kid in his class who survived a school shooting. Two years after the infamous event, twelve-year-old Simon and his family move to the National Quiet Zone—the only place in America where the internet is banned.

Did Eric cause the accident that leaves Dani unable to do the one thing in the world she most cares about?

But Dani is hurting too much to want Eric to pursue the truth—she just wants to shut him out and move on. Besides, Eric has a history of dropping things he starts.
